Every time someone visits one of your short links and gets redirected, that's a Smart Click. Your account tracks two numbers for each link: total clicks (all time) and clicks this month, which resets at the start of each billing month and counts against your plan's monthly click allowance.
Tracking where a click came from
Add a tag to the end of any short link to see exactly where a click came from in your analytics — for example:
go.affi.link/yourcode?src=yt-video-1
Clicks through that tagged version show up under their own tag in Analytics, separate from your general totals, so you can tell which post, video, or email actually drove the click.
What happens if you go over your monthly allowance: see What happens when I reach my click limit?
